BLdTTlNG-PAD.

SPECIFICATION forming part of Letters Patent No. 736,289, dated August 11, 1903.

Application filed April 13, 1903 T0 aZZ whom it may concern:

Be it known that I; WILLIAM AMAKER MUR- RAY, acitizen of the United States, residing at Washington, in the District of Columbia, have invented new and useful Improvements in Blotting-Pads, of which the following is a specification.

This invention relates'to blotting-pads, and. particularly to means for holding the clamping-plate inreliable connection to the body of the padaud overcome the disadvantages resident in blotting-pads as ordinarily constructed and wherein a screw extends upwardly from the center of the body through an opening in the clamping-plate to receive the handle or grip. In this ordinary or com- .mon form of blotting-pad the threads of the screw, which is usually wood, become worn or broken and the clamping-plate soon Works loose and fails to hold the strips of blottingpaperon the body with that firmness which is necessary to render a blotting-pad effective. The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter describedand claimed.

In the drawings, Figure l is a perspective view of a blotting-pad embodying the features of the invention. Fig. 2 is a vertical longitudinal section through the center thereof. Fig.3 is a detail perspective View of a nut mounted in the body to receive the holding device. Fig. 4 is an elevation of a different'form of holding device or fastening means.

Similar numerals of reference are employed to indicate corresponding parts in the several views. p.

The numeral 1 designates a body which is of the usual form and has a lower convex face and an upper flat side. In the center of the body a recess 2 is formed to receive a circular shouldered nut 3, said recess being formed in the under side or face of the body. The preferred form of the nut 3 comprises a lower disk 4:, which serves as a head, and an integral collar 5 of considerably less diame ter, both the disk and collar having a screwthreaded bore 6 extending centrally therethrough. The recess 2 is of the same shape as the nut, and the latter is so disposed as to have the disk or head 4 at thebottom. In

line with the bore 6 the body has an opening 7 formed therein, which extends through the upper side of the body, and cooperating with the latter is a clamping-plate 8, also having an opening 9 through the center thereof. A grip or handle 10 is arranged on the clamping-plate 8, and projecting centrally therethrough is a holding or fastening means in the form of a bolt 11, having its head countersunk in the upper end of the said grip or handle and its lower end 12 screw threaded to engage the bore 6 of the nut 3. The bolt 11 is applied to the grip or handle in such manner as to rotate therewith, and the nut shaped.

The lower side of either form of nut is flush with the lower face or side of the body 1 when properly assembled in relation to said body, and in the use of the improved blotting-pad strips of blotting-paper of suitable length are pressed against the lower convex face of the body 1 and the ends thereof turned over the upper side of the body. The

clamping-plate 8 is then applied over the body, and the ends of the strips of blottingpaper and the grip 10 and bolt 11 carried thereby are applied so that the said bolt will project through the openings 9and 7and engage the bore 6 of the nut 3 or that of the nut 12, as the case may be. The grip is then rotated to bring the lower end thereof in close contact with the clam ping-plate to secure the strips of blotting-paper firmly to the body. When it is desired to remove one of the strips of blotting-paper, the grip 10 is rotated in a reverse direction to release or loosen the bolt 11.

The improved form of blotter will be found exceptionally durable, and all the parts may be constructed of Wood except the nut and Having thus fully described the invention,

What is claimed as new is- 1. A blotting-pad, comprising a body, having a nut countersunk in the center of the lower portion thereof, and an opening in line with the bore of the nut, a clamping-plate having a central opening therein, and a grip having a bolt extending therethrough and retatable therewith, said bolt being adapted to extend through the opening in the clampingplate and engage the nut countersunk in the body.

2. A blotting-pad, comprising a body, having a nut countersunk in the lower center portion thereof, a clamping-plate, and a'grip having a bolt extending therethrough and retatable therewith, said bolt being longer than
